A Original application filed October 24, 1912, Serial No. 727,544. Divided and this application filed June 26,

' A 1914.. Serial No. 847,555

To all wh o'm' it may concern Be t known that I, CHARLES D; DEWEY,

' citizen of the United States of America, and

resident of LongBeach, Los Angeles county, California, have invented a new and useful Driving lvie'chanism' of which the following is aspecificatjionii The object of this invention' is to pro ride improved means for driving the dolly mechanism of a washing machine from beneath a tub without any devices on or through the cover of the tub. I

A further object of this invention is to provide improved means for carrying a dolly deviceonroller -bearings. I

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my 'cl'ainisand illustrated by the accompanying originallyincluded in and hasbeen divided from my application Number 727,544 for washing machine, filed October 24:, 1912. In the construction of thedevice as shown the numeralIO designates a tub preferably of'cylindricalform, inadeof Wooden staves or sheetm tal and a plurality of legs suitably connected and bound together, and ham ing an inclined bottom 11 directed toward a drainage faucet 12 of globe shape inthe wall which is adapted to retain the "dirt which flows to it On the inclined bottom. The tub also is provided with suitable handles such a's13 anda removable and 1-'e'placea}; le cover 14, which cover may be of sheet metal if desired. I A I j 'A cap '22, of metal, is mounted on the upper end o'f the cylinder 20and is secured rigidly thereto, and said cap is formed with a ball-race in its upper-surface concentric with the center of the cylinder andcap. A

tubular shaft 23 is mounted for rotation through the-"cap 22 andbo'ttomll, in upright position; A gear 24 fiXed to the lower end 01": the tubular shaft 23 and is adapted to be driven by any suitable mechanism (not shown) beneath the tub. A bearing plate 25 is mounted on the bottom 11 of the tub and is formed with a ball-race in its upper face corresponding with a ball-race in the lower face of the gear 2i, and bearing balls 26 are interposed between said races. A spindle 27 is mounted in upright position through the center of the tubular power shaft 23 and has its lower end supported by the bearing plate 25. An internal gear 28, formed with a ball-race in its lower surface,is superposed on the cap 22 and is supported by balls 29 in the races of said cap and gear. The internal gear 28 is mounted loosely and for rotary oscillation on the spindle 27 The internal gear 28 is formed with downwardly extending arms 30, preferably four in number, and spring'clamping members 31 are hingedon horizontalaxes to the lower ends of said armsand extend radially of the'tub, approximately to the center of the space between the concentric rubbing surfaces in the tub. A tubular cap 32, is mounted on the projecting upper end of the spindle 27 and-is adjustable altitudi nally thereon and held in such adjustment by a set screw 33. The cap 32 isformed with abearing surface in its top anda spider dolly 3%, with'four radiating arms, is formed with a downwardly projecting pivot adapted to rest and turn in said bearing. The arms of the; dolly 34 extend" outwardly and downwardly and are adapted to be engaged and firmly held by the" spring clamps 3 1.

36 meshes, during part of each revolution, with one of a pair of driving pinions 37, 38 which are in train with the internal gear 28 and are adapted to drive said internal gear somewhat less than one-half a revolution in the same direction as the mutilated gear is driven. The mutilated gear 36 is in mesh, during the major part of the remainder of each revolution, with a reversinggear 39 opposite the pinion 37 and in train with the internal gear 28; and said'reversing gear is adapted to drive said internal gear, some what less than one-half a revolution in a directionopposite to that in'which the mutilated gear is driven. Thus is provision made for transforming rotary motion of the tubular 'shaft23 and mutilated gear 36 into oscillatory motion of the internal gear and agitating devices, 1 through the arms 30 and clamps 31. 1 A'cap 40 is provided and is adapted to be superposed over the gears 28, 37, 38 and 39 before the dolly 34 is placed in position on the'cap 32. It is the function of the cap 40 to guard and cover the gearing,

and shed Water therefrom.-

In practical use the dolly 34b is removed 1 manually by'disengaging its arms from the clamps 31 and lifting from the pivotal connection on the upper end of thecap 32. The dolly is then replaced, and the altitude of the same 1s adjusted by means, of the set screw 33,- depending upon the amount of clothes in the tub.' 7 Power isapplied' to the gear Qet-to the endof driving the shaft 23, mutilated gear 36, and thence the gear 39 and pinions 37, 38 alternately,'whereby'the internal gear 28 receives an oscillatory motion and transmits the same to the dolly. The" hinged paddles 35, which preferably are corrugated transversely, stir and agitate the.,clothes, and press downwardly thereon at every reverse motion. This action, together with the concentric outer and inner wash-boards of the tub, accomplish the washing operation easily and quickly.

7' The weight of the dolly rests entirely uponthe stationary shaft or spindle 27 and does not at all impede the gearing, thus securing a very easy starting and light running driving mechanism, which end also is facilitated by the ballbearing supports of a the gears Ql and 28.
